Bug 1370668 - Do not assume that uid and deviceID will be present in the sync telemetry bundle r=nalexander It's possible that a sync fails very early, for example while talking to the token server. In that case, we wouldn't have uid/deviceID available in the sync telemetry bundle. MozReview-Commit-ID: 7OB1Er37qo8
